From the Practical to the Sapient: Curriculum Judgment Beyond Schwab
Abstract Joseph Schwab's “practical turn” remains a defining moment in curriculum theory. His practical papers of the late 1960s and early 1970s sought to restore professional judgment to a field dominated by technical rationality and policy prescription.

ABSTRACT Aim To examine and compare global nursing education content, institutional support, and workload‐related factors among nurse educators in Japan and China. “Global nursing education” refers to educational interventions that enable nursing students to develop the knowledge, skills, practical experience, and cultural competence needed to provide ...

Abstract Bouncing packets are quasi‐periodic microbursts separated by the electron bounce period. Solar Anomalous and Magnetospheric Particle Explorer observations revealed relativistic (>1 MeV) inner‐belt bouncing packets with “crown,” “decaying,” and “flat” envelopes.

Abstract Microbursts are thought to be a key contributor to radiation belt electron loss, with chorus waves considered a primary driver of this precipitation. However, the conditions under which chorus waves produce MeV electron loss remain poorly constrained.

Evolution of Reversed Electron Energy Spectra in Earth’s Radiation Belts Observed by CIRBE
Abstract Following an intense geomagnetic storm (Dst < −150 nT) on 5 November 2023, electron fluxes in the outer radiation belt were reduced by more than three orders of magnitude at energies below ∼700 keV while they were enhanced at ∼1–3 MeV, leading to reversed energy spectra.

Chorus Element Repetition: Roles of Energetic Electron Injection and Nonlinear Wave Growth
Abstract Chorus waves are coherent whistler‐mode emissions in Earth’s magnetosphere and play a key role in the acceleration and loss of radiation belt electrons. Their spectra commonly consist of discrete and repetitive elements, yet the mechanism governing this repetition is not fully understood.

Substorm Effects on Chorus Emissions Modulated by ULF Waves
Abstract Although cross‐scale wave‐particle interactions play a critical role in energy transfer in the magnetosphere, the influence of geomagnetic activity on the physical mechanisms involved remains unclear. In this study, we investigate this question by analyzing Van Allen Probes‐A observations of an event occurring on 25 July 2016.

Abstract High‐altitude balloon measurements were conducted over southern Israel (30°35′N, 34°45′E; 850 m a.s.l., geomagnetic rigidity cutoff 10.3 GV) to characterize the vertical profiles of atmospheric ionization and radiation up to ∼35 km. Six balloon launches between October 2014 and August 2016 recorded the variability of atmospheric ionization ...

T‐Shaped Stibenium(III) Cation: Hydrostibination Without Sb─H Bond
A cationic, structurally constrained stibenium platform mediates anti‐Markovnikov hydrostibination of alkenes via element–ligand cooperativity (ELC), thereby bypassing the need for weak Sb─H bonds. ABSTRACT The hydrostibination of alkenes represents a largely underdeveloped transformation, owing to the intrinsic lability of the required Sb─H reagents ...
